During the ongoing All Sky Automated Survey for SuperNovae (ASAS-SN or "Assassin"), using data from the quadruple 14-cm "Brutus" telescope in Haleakala, Hawaii, we discovered a new transient source, most likely a supernova, in the galaxy PGC 006399:

ASASSN-14kg was discovered in images obtained on UT 2014-11-17.36 at V~16.4 mag. We also marginally detect the object in images obtained on UT 2014-11-12.46 (V~16.9), but we do not detect (V>16.9) the object in images taken on UT 2014-11-11.38 and before. An image obtained on 2014-11-17.74 by J. Nicolas using a 0.41-m telescope at Observatoire Chante-Perdrix-Dauban, France, confirms the discovery of the transient. This figure shows the archival DSS image of the host (left) and the J. Nicolas confirmation image (right). The red arrow indicates the position of the transient in the J. Nicolas image.

The position of ASASSN-14kg is approximately 4.1" South and 0.7" West from the center of the galaxy PGC 006399 (z=0.014477, d=56.5 Mpc, via NED), giving an absolute V-band magnitude of approximately -17.5 (m-M=33.76, A_V=0.127). Follow-up observations are encouraged.

We thank LCOGT and its staff for their continued support of ASAS-SN. For more information about the ASAS-SN project, see the ASAS-SN Homepage and the list of all ASAS-SN transients.
